This white, bumpy material is called Expanded Polystyrene Foam, commonly known as Styrofoam.
It’s widely used for packaging (like protecting electronics and appliances), insulation, and sometimes in crafts or model making. The bumpy texture comes from thousands of tiny polystyrene beads fused together.
While “Styrofoam” is the most popular name in many countries, it actually has different names depending on where you are:
• Some places just call it “foam”
• Others use “polystyrene” or “EPS foam”
• In certain countries it has a completely different local name
